Description

【０００１】
【発明の属する技術分野】
本発明は、集積状態の商品を最下位に位置する商品から順次投出する自動販売機の商品投出装置に関する。
【０００２】
【従来の技術】
従来、この種の自動販売機の商品投出装置としては、例えば特開平８−３１５２４０号公報に記載の構成が知られている。
【０００３】
この特開平８−３１５２４０号公報に記載の自動販売機の商品投出装置は、商品を集積して収納する収納する複数の商品収納部の下部に、集積状態の最下位に位置する商品から順次投出する商品投出部がそれぞれ配設されている。この商品投出部は、複数のプーリに掛け渡され商品収納部の開口する底面を閉塞して回行移動可能に無端状のベルトが掛け渡されている。また、ベルトにはモータなどの駆動手段の駆動により回転するプーリが係合され、駆動手段の駆動によりベルトが回行する。さらに、ベルトの外面には、ベルトの回行に伴って移動し、商品の側面に当接して商品を投出する投出爪部が一体的に設けられている。
【０００４】
そして、利用者が所望の商品を選択する操作により、商品投出部の駆動手段が駆動してベルトが回行することにより、一体的に移動する投出爪部が集積収容されている最下位の正面の側面に当接し、この投出爪部に押し出されるように商品が１つ搬出される。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記特開平８−３１５２４０号公報に記載の自動販売機の商品投出装置では、商品収納部に対してそれぞれ駆動手段を備えた商品投出部が設けられているため、複数種類の商品を収容する自動販売機においては、多量の駆動手段が必要となり、配線や駆動手段の組み付けなどの製造が煩雑で、製造性の向上が図れないとともに、コストの低減が困難で、重量が増大する問題がある。
【０００６】
本発明は、このような問題点に鑑みてなされたもので、製造性が向上するとともにコストが低減する軽量小型化の自動販売機の商品投出装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
請求項１記載の自動販売機の商品投出装置は、隣接され商品を集積状態で収納する一対の商品収納部と、正逆反転可能な無端ベルト状の投出ベルト、およびこの投出ベルトの外周面における周方向の複数位置に設けられ正転時には前記商品収納部内に収納された最下位に位置する前記商品を投出し逆転時には前記商品を投出しない投出部材を備え、前記各商品収納部の下部にそれぞれ設けられた一対の商品投出手段と、これら商品投出手段を動作させる正逆回転可能な出力軸を備えた駆動手段と、この駆動手段の出力軸に直交しかつ水平方向に沿い互いに同軸上に位置する一対の回転軸を備え、前記駆動手段の出力軸の正転時に一方の回転軸を通じて一方の商品投出手段の投出ベルトを正転させるとともに他方の回転軸を通じて他方の商品投出手段の投出ベルトを逆転させ、前記駆動手段の出力軸の逆転時に一方の回転軸を通じて一方の商品投出手段の投出ベルトを逆転させるとともに他方の回転軸を通じて他方の商品投出手段の投出ベルトを正転させる駆動伝達手段とを具備し、前記駆動手段および前記駆動伝達手段を備える駆動部が、前記一対の商品投出手段の間に位置して区画形成されているものである。
【０００８】
そして、駆動伝達手段により、正逆回転可能な駆動手段の正逆回転に対応して、商品投出手段のいずれか一方を正転し、隣接され商品を集積状態で収納する一対の商品収納部のいずれか一方に収納された最下位に位置する商品を投出し、いずれか他方を逆転して商品を投出させないため、１つの駆動手段にて２つの商品収納部内の商品を適宜投出可能で、商品収納部に対応して駆動手段を設ける必要がなく、製造性が向上するとともにコストが低減し、軽量小型化が容易に図れる。
【０００９】
請求項２記載の自動販売機の商品投出装置は、隣接され商品を集積状態で収納する一対の商品収納部と、正逆反転可能な無端ベルト状の投出ベルト、およびこの投出ベルトの外周面における周方向の複数位置に設けられ正転時には前記商品収納部内に収納された最下位に位置する前記商品を投出する投出部材を備え、前記各商品収納部の下部にそれぞれ設けられた一対の商品投出手段と、これら商品投出手段を動作させる正逆回転可能な出力軸を備えた駆動手段と、この駆動手段の出力軸に直交しかつ水平方向に沿い互いに同軸上に位置する一対の回転軸を備え、前記駆動手段の出力軸の正転時に一方の回転軸を通じて一方の商品投出手段の投出ベルトを正転させるとともに他方の回転軸から他方の商品投出手段の投出ベルトへの駆動の伝達を遮断し、前記駆動手段の出力軸の逆転時に一方の回転軸から一方の商品投出手段の投出ベルトへの駆動の伝達を遮断するとともに他方の回転軸を通じて他方の商品投出手段の投出ベルトを正転させる駆動伝達手段とを具備し、前記駆動手段および前記駆動伝達手段を備える駆動部が、前記一対の商品投出手段の間に位置して区画形成されているものである。
【００１０】
そして、駆動伝達手段により、正逆回転可能な駆動手段の正逆回転に対応して、商品収納部の下方にそれぞれ配設した商品投出手段のいずれか一方を正転し、隣接され商品を集積状態で収納する一対の商品収納部のいずれか一方に収納された最下位に位置する商品を投出し、いずれか他方への駆動の伝達を遮断して商品を投出させないため、１つの駆動手段にて２つの商品収納部内の商品を適宜投出可能で、商品収納部に対応して駆動手段を設ける必要がなく、製造性が向上するとともにコストが低減し、軽量小型化が容易に図れる。
【００１１】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
【００１２】
図７および図８において、１は、例えば、たばこの自動販売機で、この自動販売機１は、前面を開口する略箱状の本体２と、この本体２の前面を開閉可能に取り付けられた扉体３とを備えている。そして、本体２内には、平面が略水平方向に沿い長手方向が本体２の左右方向に沿って設けられた平板状の棚板４が上下に複数、例えば３枚設けられている。また、本体２内には、平面が本体２の前後方向に沿い長手方向が上下方向に沿って棚板４，４の長手方向の一側に位置して側板部５が設けられている。さらに、これら棚板４，４上には、例えばたばこなどの商品を集積状態、すなわち１つずつ上下方向に積み重ねた状態で収納する商品収納部としての商品コラム６が、前面に対して平面状に複数列および複数段、例えば６列で３段配設されている。そして、本体２内には、各種部位に電力を供給する電源装置７および各種部位の制御を行う図示しない制御装置が配設されている。
【００１３】
また、扉体３の前面には、商品コラム６に収容される例えばたばこなどの商品９に対応する図示しない見本を陳列する見本展示部10と、見本に対応して複数、すなわち商品コラム６に対応して１８個設けられた選択ボタンと、商品が払い出される商品取出口を前方に向けて開口する商品取出部11と、硬貨が投入される硬貨投入口および紙幣が投入される紙幣投入口を開口するとともに釣銭などの硬貨を返却する硬貨返却口を開口し、硬貨を返却する操作部としての返却レバーを備え、投入された硬貨や紙幣を検出、貯留および返却などの貨幣を処理する貨幣処理部12とが設けられている。さらに、扉体３の後面には、扉体３が本体２の前面を閉塞した状態で商品コラム６の前面に近接し、各商品コラム６，６から投出される商品９を受け入れる商品受入口13，13を開口し、商品取出部11に受け入れた商品９を搬出する商品シュート14が設けられている。
【００１４】
一方、商品コラム６は、図６に示すように、棚板上に適宜間隔で配設された商品投出ユニット21と、この商品投出ユニット21の上方に位置して取り付けられるコラム部材22とにて構成されている。そして、コラム部材22は、平板状の後面部23を有している。また、この後面部23には、上下方向の一縁に前方に向けて略垂直に折曲された第１の仕切板24が形成されている。さらに、後面部23の略中央には、第１の仕切板24と略平行で、商品９を集積状態で収納すなわち１個ずつ積み重ねて収納する第１の収納空間25および第２の収納空間26を区画する第２の仕切板27が設けられている。なお、第１の収納空間25は第１の仕切板24と第２の仕切板27とにて区画される。第２の収納空間26は第２の仕切板と、隣接される他のコラム部材22の第１の仕切板24あるいは本体２の側板部５とにて区画される。また、第１の仕切板24および第２の仕切板27の間隔や第２の仕切板27の後面部23に対する位置は、収納する商品の大きさに対応して適宜設定される。
【００１５】
また、第１の仕切板24および第２の仕切板27の後面部23側と反対側である前側縁には、後面部23と略平行に同方向に向けて、すなわち第１の収納空間25および第２の収容空間26の前面の一部を覆うように折曲され、第１の収納空間25および第２の収納空間26内に集積状態で収納した商品９の脱落を防止する前支え部28，28が形成されている。なお、これら前支え部28，28は、折曲方向側の縁である先端縁と第２の仕切板27、あるいは、隣接されたコラム部材22の第１の仕切板24または本体２の側板部５との距離が、商品９を傾けることにより挿入可能な補充開口29を開口する間隙を介する寸法に設定されて形成されている。
【００１６】
さらに、第１の仕切板24は後面部23および第２の仕切板27より下方に長く形成され、第１の仕切板24の下端縁には、下方に向けて舌片状に突出し棚板４に設けられた差込孔部31に差し込み保持される第１の差込突起32が設けられている。また、第２の仕切板27の下端縁には、第１の差込突起32と同様に下方に向けて舌片状に突出する第２の差込突起33が設けられている。
【００１７】
一方、商品投出ユニット21は、例えば弾性を有する合成樹脂製のケース体35を備え、このケース体35内には、図１ないし図３に示すように、略平行にリブ36，36が設けられている。そして、ケース体35内には、リブ36，36により、コラム部材22の第１の収納空間25および第２の収納空間26の下方に位置し、これら第１の収納空間25および第２の収納空間26に集積状態で収納された商品９を最下位から１つずつ取り出す商品投出手段としての第１の投出機構部37および第２の投出機構部38と、これら第１の投出機構部37および第２の投出機構部38間にこれら第１の投出機構部37および第２の投出機構部38を駆動する駆動部39とが、サンドイッチ状に位置して区画形成されている。そして、ケース体35の下面には、棚板４に取り付けられる係止爪部40が下方に向けて突設されている。
【００１８】
また、ケース体35の上部一縁は、商品９が引っ掛かったり凹むなどの損傷を生じることなく円滑に投出するために円弧状に面取りされた曲面部42となり、この曲面部42が位置する端面が商品９の投出側となる本体２の前面に向く状態に棚板４に取り付けられる。さらに、ケース体35の略中央、すなわち駆動部39に位置する部分の上面には、コラム部材22の第２の仕切板27に設けられた第２の差込爪部が挿入係合される挿入孔部43が設けられている。
【００１９】
そして、第１の投出機構部37および第２の投出機構部38には、軸方向が水平方向かつ本体２の左右方向に略沿い、前後方向に略平行にそれぞれ一対ずつリブ36およびケース体35の側板部44に回転自在に軸支された回転シャフト45に一体的に前プーリ46および後プーリ47が設けられている。なお、後プーリ47を設けた回転シャフト45の駆動部39側の端部は、駆動部39内に位置してリブ36を貫通するように回転自在に軸支されている。また、これら前プーリ46および後プーリ47には、無端ベルト状の第１の投出ベルト48および第２の投出ベルト49が回行自在にそれぞれ掛け渡されている。
【００２０】
さらに、これら第１の投出ベルト48および第２の投出ベルト49の外周面には、複数、例えば周方向で略２等分する位置に２つの投出部材51，51がそれぞれ設けられている。この投出部材51は、軸方向が第１の投出ベルト48および第２の投出ベルト49の幅方向に略沿って設けられたシャフト52に一端側が回動自在に軸支された略平板状の押出部53を備えている。また、投出部材51は、押出部53の一端側を第１の投出ベルト48および第２の投出ベルト49の外面から離間、例えば第１の投出ベルト48および第２の投出ベルト49の外面に対して略３０°の角度となる方向に回動付勢するトーションばねや板ばね、コイルスプリングなどの図示しない付勢手段にて付勢されている。なお、投出部材51は、第１の投出ベルト48および第２の投出ベルト49が正転する方向側が回動する側となるように軸支されている。
【００２１】
そして、第１の投出ベルト48および投出部材51にて第１の投出機構部55が構成され、第２の投出ベルト49および投出部材51にて第２の投出機構部56が構成される。
【００２２】
また、第１の投出機構部55および第２の投出機構部56には、図６に示すように、上端面より先端部が進退可能に突出する検出部58を有した商品検出部59がそれぞれ配設されている。
【００２３】
一方、駆動部39には、軸方向が前後方向に沿った出力軸61を有した正逆回転可能な駆動手段としての駆動モータ62が設けられている。そして、この駆動モータ62の出力軸61には、駆動伝達手段を構成するカサ歯ギヤ63が一体的に設けられている。また、駆動部39には、軸方向が駆動モータ62の出力軸61に略直交しかつ水平方向に沿い互いに略同軸上にカサ歯ギヤ63の径方向に位置する一対の回転軸65，65が回転自在に配設されている。そして、これら回転軸65，65には、カサ歯ギヤ63に係合する駆動伝達手段を構成する第１の伝達カサ歯ギヤ67a および第２の伝達カサ歯ギヤ67b がそれぞれ設けられている。さらに、第１の伝達カサ歯ギヤ67a が設けられた回転軸65には駆動伝達手段を構成する第１の伝達小ギヤ68a が一体的に設けられ、第２の伝達カサ歯ギヤ67b が設けられた回転軸65には駆動伝達手段を構成する第２の伝達小ギヤ68b が一体的に設けられている。また、駆動部39には、第１の伝達小ギヤ68a に係合する駆動伝達手段を構成する第１の伝達大ギヤ69a および第２の伝達小ギヤ68b に係合する駆動伝達手段を構成する第２の伝達大ギヤ69b が、後プーリ47，47を軸支する回転シャフト45，45にそれぞれ一体的に設けられている。
【００２４】
そして、第１の伝達カサ歯ギヤ67a 、第１の伝達小ギヤ68a および第１の伝達大ギヤ69a にて第１の駆動伝達部70が構成され、第２の伝達カサ歯ギヤ67b 、第２の伝達小ギヤ68b および第２の伝達大ギヤ69b にて第２の駆動伝達部71が構成されている。また、これら第１の駆動伝達部70および第２の駆動伝達部71とカサ歯ギヤ63とにて、駆動モータ62の駆動により第１の投出ベルト48および第２の投出ベルト49を回転させる駆動を伝達する駆動伝達手段72が構成される。
【００２５】
この駆動伝達手段72は、駆動モータ62の駆動を、カサ歯ギヤ63から第１の伝達カサ歯ギヤ67a および第２の伝達カサ歯ギヤ67b 、第１の伝達小ギヤ68a および第２の伝達小ギヤ68b 、第１の伝達大ギヤ69a および第２の伝達大ギヤ69b を介して後プーリ47，47を一体的に設けた回転シャフト45，45に伝達し、後プーリ47，47が回転することにより第１の投出ベルト48および第２の投出ベルト49をそれぞれ反対方向に回転させる。すなわち、例えば駆動モータ62が正転する場合、図４に示すように、第１の投出ベルト48が投出部材51にて商品９を第１の収納空間25から押し出す方向に正転し、第２の投出ベルト49が投出部材51の退避により商品９を押し出さない方向に逆転する。また、駆動モータ62の回転方向が反転して逆転することにより、図５に示すように、第１の投出ベルト48が投出部材51の退避にて商品９を押し出さない方向に逆転し、第２の投出ベルト49が第２の収納空間26から商品９を押し出す方向に正転する。
【００２６】
なお、駆動モータ62が駆動していない状態では、投出部材51は、図３に示すように、前プーリ46および後プーリ47に対応する位置、すなわち第１の収納空間25および第２の収納空間26に位置せず、前後に位置する状態で待機状態となる。そして、駆動モータ62は、第１の投出ベルト48および第２の投出ベルト49が半周、すなわち、待機状態に位置する投出部材51の一方が第１の収納空間25および第２の収納空間26を通過して反対側の対称位置の待機状態に位置すると停止するように駆動制御される。
【００２７】
また、商品投出ユニット21の上方にコラム部材22が取り付けられることにより、商品投出ユニット21の上面と前支え部28の下端縁との間には商品９が通過可能な投出開口部74が開口されている。また、商品投出ユニット21の上面と後面部23の下端縁との間には、第１の投出ベルト48および第２の投出ベルト49にそれぞれ設けられた投出部材51が通過可能でかつ商品９が非通過可能な逃げ開口部75が開口形成されている。
【００２８】
次に、上記実施の形態の組立動作を説明する。
【００２９】
あらかじめ本体２に取り付けられた棚板４に開口する図示しない取付孔に、商品投出ユニット21の係止爪部40，40を係合して、商品投出ユニット21を取付固定する。次に、商品投出ユニット21の挿入孔部43にコラム部材22の第２の仕切板27に設けた第２の差込突起33を挿入保持するとともに、棚板４に設けた差込孔部31に第１の差込突起32を挿入保持してコラム部材22を取付固定する。
【００３０】
そして、商品投出ユニット21の図示しない駆動モータ62への電力供給用の電線や商品検出部の信号を伝達するための信号線に設けられた図示しないコネクタをあらかじめ本体２に組み付けられた図示しないコネクタに接続する。
【００３１】
一方、商品投出ユニット21の交換などの場合には、コラム部材22を取り外し、商品投出ユニット21の弾性を有する係止爪部40，40を弾性変形して棚板４の取付孔から外して、商品投出ユニット21を取り外す。
【００３２】
次に、上記実施の形態の商品を投出する動作を図９および図１０を参照して説明する。
【００３３】
まず、各商品コラム６，６に商品９を集積状態で収納し、電源を投入して、図３に示す投出部材51，51が第１の収納空間25および第２の収納空間26に位置しない待機状態とする。なお、この待機状態では、図３に示すように、投出部材51，51は第１の収納空間25および第２の収納空間26に位置せず、前プーリ46および後プーリ47に対応して前後に位置する状態となっている。また、商品コラム６の第１の収納空間25および第２の収納空間26に商品９が収納されているため、商品検出部59の検出部58が商品９の自重により押された状態となってケース体35の上端面から後退して商品９を検出することにより、図示しない制御装置が『品切れ』の表示をしない制御をする。
【００３４】
そして、この待機状態で利用者が購買動作、すなわち貨幣を投入し、選択ボタンを操作する。この選択ボタンの操作により、制御装置は、対応する商品コラム６の駆動モータ62を駆動する。
【００３５】
すなわち、例えば選択された商品９が所定の商品コラム６の第１の収納空間25に収納した商品９である場合、その商品コラム６の駆動モータ62を正転する。この駆動モータ62の正転により、図４に示すように、駆動モータ62の出力軸61に設けられたカサ歯ギヤ63が正転し、このカサ歯ギヤ63に係合する第１の駆動伝達部70の第１の伝達カサ歯ギヤ67a および第２の駆動伝達部71の第２の伝達カサ歯ギヤ67b がそれぞれ反対方向に回転する。そして、これら第１の伝達カサ歯ギヤ67a および第２のカサ歯ギヤ67b にそれぞれ係合する第１の伝達小ギヤ68a および第２の伝達小ギヤ68b と、これら第１の伝達小ギヤ68a および第２の伝達小ギヤ68b に係合する第１の伝達大ギヤ69a および第２の伝達大ギヤ69b とを介して、第１の投出機構部37の後プーリ47および第２の投出機構部38の後プーリ47に反対方向の回転が伝達される。
【００３６】
そして、第１の投出機構部37の後プーリ47は正転して第１の投出ベルト48が正転、すなわち投出部材51，51の押出部53，53の付勢手段にて付勢されて第１の投出ベルト48の外面から離間する側が移動方向の前側となるように第１の投出ベルト48が回転する。
【００３７】
この第１の投出ベルト48の正転により、図９（ａ）に示すように、投出部材51の押出部53の回動側の端部縁が逃げ開口部75から第１の収納空間25内に移動し、図９（ｂ）に示すように、この第１の収納空間25内に集積状態で収納した最下位の商品９に押出部53が当接して第１の収納空間25から投出開口部74を介して排出し、図９（ｃ）に示すように、商品９を商品シュート14に送り出す。この商品シュート14に送り出された商品９は、商品シュート14を通過して商品取出口を開口する商品取出部11に投出される。そして、投出部材51，51が待機状態の位置まで移動すると、制御装置は駆動モータ62の駆動を停止し、再び待機状態となる。また、最下位の商品９が押し出されることにより、第１の収納空間25内に位置する商品９は、図９（ｃ）に示すように、全体的に下方に移動し、再び商品検出部の検出部58を押し込む。なお、商品９がすべて投出された場合には、商品検出部59の検出部58が押されなくなり、制御装置が商品９のないことを認識して『売り切れ（品切れ）』を表示する。
【００３８】
一方、第２の投出機構部38の後プーリ47は逆転して第２の投出ベルト49が逆転、すなわち投出部材51，51の押出部53，53の軸支された側が移動方向の前側となるように第２の投出ベルト49が回転する。
【００３９】
この第２の投出ベルト49の逆転により、図１０（ａ）に示すように、投出部材51の押出部53の軸支側が投出開口部74から第２の収納空間26内に移動する。そして、押出部53は、図１０（ｂ）に示すように、商品９の自重により付勢手段の付勢に抗して第２の投出ベルト49に向けて回動し、押出部53の回動側が最下位の商品９の下面を滑動するように移動する。ここで、最下位の商品９はコラム部材22の後面部23に位置決めされた状態となっていることから、商品９が第２の収納空間26から投出されない。そして、投出部材51，51が待機状態の位置まで移動して駆動モータ62の駆動が停止し、再び待機状態となる。
【００４０】
また、選択ボタンの操作により選択された商品９が所定の商品コラム６の第２の収納空間26に収納した商品９である場合には、その商品コラム６の駆動モータ62を逆転し、図５に示すように、第１の投出ベルト48を逆転させるとともに第２の投出ベルト49を正転させ、同様にして第２の収納空間26内に集積状態で収納された最下位の商品９を投出する。
【００４１】
このように、正逆回転可能な駆動モータ62の正逆回転に対応して、駆動伝達手段72により隣接され商品９を集積状態で収納する一対の商品コラム６の第１の収納空間25および第２の収納空間26の下方にそれぞれ配設した第１の投出機構部37および第２の投出機構部38のいずれか一方を正転して収納された最下位に位置する商品９を投出し、第１の投出機構部37および第２の投出機構部38のいずれか他方を逆転して商品９を投出しないため、１つの駆動モータ62にて２つの第１の収納空間25および第２の収納空間26内に収納した商品９を適宜投出でき、商品９の種類すなわち商品９を収納する箇所に対応して駆動モータ62をそれぞれ設ける必要がなく、特にコイルを有した重量の重い駆動モータ62の数を低減でき、製造性を向上できるとともにコストを低減でき、容易に軽量小型化できる。
【００４２】
また、第１の投出ベルト48に回動可能に付勢手段にて付勢された押出部53を軸支した投出部材51を設けたため、駆動伝達手段72を単に第１の投出ベルト48および第２の投出ベルト49を反対方向に回転させるように駆動を伝達する構成とすることにより、１つの駆動モータ62で２種類の商品９を適宜投出できる構成が容易に得られる。
【００４３】
そして、弾性を有する合成樹脂製のケース体35を用いたため、駆動モータ62の駆動を駆動伝達手段72にて第１の投出ベルト48および第２の投出ベルト49に伝達する際に生じる騒音の発生を抑制できる。
【００４４】
なお、上記実施の形態において、駆動伝達手段72として、カサ歯ギヤ63、第１の駆動伝達部70および第２の駆動伝達部71にて構成したが、駆動手段の正逆回転に対応して第１の投出機構部37および第２の投出機構部38が適宜反対方向に駆動するいずれの構成でもできる。なお、カサ歯ギヤ63を用いることにより、簡単な構成で容易に反対方向に駆動できる。
【００４５】
次に、本発明の他の実施の形態を図１１ないし図１５を参照して説明する。
【００４６】
この図１１ないし図１５に示す実施の形態は、上記図１ないし図１０に示す実施の形態の駆動伝達手段72を、駆動モータ62の正逆回転に対応して、第１の投出機構部37および第２の投出機構部38のいずれか一方を正転して収納した商品９を投出し、第１の投出機構部37および第２の投出機構部38のいずれか他方への駆動の伝達を遮断して商品９を投出しない構成としたものである。
【００４７】
すなわち、商品投出ユニット81は、上記図１ないし図１０に示す実施の形態の商品投出ユニット21と同様に、リブ36，36にて第１の投出機構部82、第２の投出機構部83および駆動部84を区画し、係止爪部40を突設したケース体35を有している。
【００４８】
そして、第１の投出機構部82および第２の投出機構部83には、図１ないし図１０に示す実施の形態の第１の投出機構部37および第２の投出機構部38と同様に、回転シャフト45に回転自在に軸支した前プーリ46および後プーリ47に掛け渡された第１の投出ベルト48および第２の投出ベルト49をそれぞれ備えている。また、これら第１の投出ベルト48および第２の投出ベルト49の外周面には、複数、例えば周方向で略２等分する位置に２つの投出部材85，85がそれぞれ設けられている。この投出部材85は、例えば合成樹脂などにて断面楔状に形成され、次第に肉薄となるように傾斜面86が設けられているとともに、肉厚部分の端面に商品を押し出す当接面87が設けられ、この当接面87が第１の投出ベルト48および第２の投出ベルト49の外周面に対して略垂直に直交するように取り付けられている。
【００４９】
一方、駆動部84は、図１ないし図１０に示す実施の形態の駆動部39と同様に、出力軸61にカサ歯ギヤ63を備えた駆動モータ62を備えている。また、駆動部84は、軸方向が駆動モータ62の出力軸61に略直交しかつ水平方向に沿い互いに略同軸上にカサ歯ギヤ63の径方向に位置する一対の回転軸65，65が回転自在に配設されている。そして、この回転軸65，65には、カサ歯ギヤ63に係合する駆動伝達手段を構成する第１の伝達カサ歯ギヤ67a および第２の伝達カサ歯ギヤ67b と、回転軸65が一方向に回転する場合のみ噛み合って回転し反対方向では空回りするワンウェイクラッチ88とがそれぞれ設けられている。さらに、これらワンウェイクラッチ88，88には、第１の伝達小ギヤ68a および第２の伝達小ギヤ68b が軸支されている。そして、第１の伝達小ギヤ68a および第２の伝達小ギヤ68b は、後プーリ47，47を軸支する回転シャフト45，45にそれぞれ一体的に設けられた第１の伝達大ギヤ69a および第２の伝達大ギヤ69b に係合される。
【００５０】
なお、ワンウェイクラッチ88，88は、例えば駆動モータが正転する場合に、図１４に示すように、カサ歯ギヤ63の回転により回転軸65，65とともに第１の伝達カサ歯ギヤ67a および第２の伝達カサ歯ギヤ67b が回転し、この回転軸65の回転により第１の伝達小ギヤ68a が回転し第２の伝達小ギヤ68b は空回りして駆動が伝達されないで回転せず、駆動モータ62が逆転する場合は、図１５に示すように、第１の伝達小ギヤ68a が空回りして駆動が伝達されないで回転せずに第２の伝達小ギヤ68b が回転するように、第１の伝達小ギヤ68a および第２の伝達小ギヤ68b が相対的に反対方向に空回りするようになっている。
【００５１】
そして、これら第１の伝達カサ歯ギヤ67a 、ワンウェイクラッチ88に軸支された第１の伝達小ギヤ68a および第１の伝達大ギヤ69a にて第１の駆動伝達部91が構成され、第２の伝達カサ歯ギヤ67b 、ワンウェイクラッチ88に軸支された第２の伝達小ギヤ68b および第２の伝達大ギヤ69b にて第２の駆動伝達部92が構成されている。また、これら第１の駆動伝達部91および第２の駆動伝達部92とカサ歯ギヤ63とにて、駆動モータ62の駆動により第１の投出ベルト48および第２の投出ベルト49を回転させる駆動を伝達する駆動伝達手段93が構成される。
【００５２】
次に、上記図１１ないし図１５に示す実施の形態の動作を説明する。
【００５３】
待機状態で利用者が購買動作、すなわち貨幣を投入し、選択ボタンを操作することにより、制御装置が対応する商品コラム６の駆動モータ62を駆動する。
【００５４】
すなわち、例えば選択された商品９が所定の商品コラム６の第１の収納空間25に収納した商品９である場合、その商品コラム６の駆動モータ62を正転する。この駆動モータ62の正転により、図１４に示すように、駆動モータ62の出力軸61に設けられたカサ歯ギヤ63が正転し、このカサ歯ギヤ63に係合する第１の駆動伝達部91の第１の伝達カサ歯ギヤ67a および第２の駆動伝達部92の第２の伝達カサ歯ギヤ67b がそれぞれ回転軸65，65と一体的に反対方向に回転する。そして、第１の駆動伝達部91のワンウェイクラッチ88は噛み合って第１の伝達小ギヤ68a が回転し、第２の駆動伝達部92のワンウェイクラッチ88は空回りして第２の伝達小ギヤ68b は回転しない。このため、第１の投出機構部82は、回転する第１の伝達小ギヤ68a に噛み合う第１の伝達大ギヤ69a に駆動が伝達されて回転し、後プーリ47が正転する。
【００５５】
そして、第１の投出機構部82の後プーリ47は正転して第１の投出ベルト48が正転、すなわち投出部材85，85の当接面87側が移動方向の前側となるように第１の投出ベルト48が回転し、第１の収納空間25内の商品９が投出される。
【００５６】
一方、第２の投出機構部83は、空回りする第２の伝達小ギヤ68b により、噛み合う第２の伝達大ギヤ69b に駆動が伝達されず、第２の伝達大ギヤ69b が回転しないことから、後プーリ47は正転しない。このため、第２の投出ベルト49が停止したままで正転しないことにより、第２の収納空間26内の商品９は投出されない。
【００５７】
また、選択ボタンの操作により選択された商品９が所定の商品コラム６の第２の収納空間26に収納した商品９である場合には、同様にその商品コラム６の駆動モータ62を逆転し、図１５に示すように、第１の投出機構部82の第１の投出ベルト48は回転せず、第２の投出機構部83の第２の投出ベルト49が正転し、第２の収納空間26内の商品９が投出される。
【００５８】
このように、正逆回転可能な駆動モータ62の正逆回転に対応して、駆動伝達手段93により隣接され商品９を集積状態で収納する一対の商品コラム６の第１の収納空間25および第２の収納空間26の下方にそれぞれ配設した第１の投出機構部82および第２の投出機構部83のいずれか一方を正転して収納された最下位に位置する商品９を投出し、第１の投出機構部82および第２の投出機構部83のいずれか他方への駆動モータ62の駆動の伝達を遮断して商品９を投出しないため、１つの駆動モータ62にて２つの第１の収納空間25および第２の収納空間26内に収納した商品９を適宜投出でき、商品９の種類すなわち商品９を収納する箇所に対応して駆動モータ62をそれぞれ設ける必要がなく、特にコイルを有した重量の重い駆動モータ62の数を低減でき、製造性を向上できるとともにコストを低減でき、容易に軽量小型化できる。
【００５９】
また、駆動モータ62の正逆回転に対応して、第１の投出機構部82および第２の投出機構部83のいずれか一方に駆動を伝達して商品９を投出しいずれか他方に駆動を伝達しない構成として、ワンウェイクラッチ88，88を用いたため、簡単な構造で１つの駆動モータ62にて２つの第１の収納空間25および第２の収納空間26内に収納した商品９を適宜投出できる。
【００６０】
さらに、商品９を投出する際に第１の投出機構部82および第２の投出機構部83のいずれか一方のみが駆動するので、図１ないし図１０に示す実施の形態に比してより騒音の発生を抑制できる。
【００６１】
また、図１ないし図１０に示す実施の形態と同様に、弾性を有する合成樹脂製のケース体35を用いたため、駆動モータ62の駆動を駆動伝達手段72にて第１の投出ベルト48および第２の投出ベルト49に伝達する際に生じる騒音の発生を抑制できる。
【００６２】
なお、上記図１ないし図１０に示す実施の形態、および、図１１ないし図１５に示す実施の形態において、たばこを販売する自動販売機について説明したが、例えば清涼飲料などの缶類など他のいずれのものでもできる。なお、コラム部材22は、商品９の形状に合わせて適宜形状に形成し、投出部材51も商品９の形状に合わせて適宜押し出したり、商品９を引っ掛けて繰り出し可能な適宜形状に形成する。
【００６３】
さらに、上記図１１ないし図１５に示す実施の形態において、駆動伝達手段93として、カサ歯ギヤ63、ワンウェイクラッチ88を備えた第１の駆動伝達部91および第２の駆動伝達部92にて構成したが、駆動手段の正逆回転に対応して第１の投出機構部82および第２の投出機構部83のいずれか一方のみ駆動を伝達して正転させて商品９を投出させるいずれの構成でもできる。
【００６４】
【発明の効果】
請求項１記載の自動販売機の商品投出装置によれば、駆動伝達手段により、正逆回転可能な駆動手段の正逆回転に対応して、商品投出手段のいずれか一方を正転して隣接された一対の商品収納部のいずれか一方の商品を投出し、いずれか他方を逆転して商品を投出しないため、１つの駆動手段にて２つの商品収納部内の商品を適宜投出でき、商品収納部に対応して駆動手段を設ける必要がなく、製造性を向上できるとともにコストを低減でき、容易に軽量小型化できる。

In addition, the first driving belt 70 and the second driving belt 71 and the bevel gear 63 rotate the first throwing belt 48 and the second throwing belt 49 by driving the drive motor 62. A drive transmission means 72 is configured to transmit the drive to be performed.
[0025]
  This drive transmission means 72 drives the drive motor 62 from the bevel gear 63 to the first transfer bevel gear 67a and the second transfer bevel gear 67b, the first transfer small gear 68a and the second transfer small gear. The rear pulleys 47 and 47 are transmitted to the integrally provided rotary shafts 45 and 45 through the gear 68b, the first transmission large gear 69a and the second transmission large gear 69b, and the rear pulleys 47 and 47 rotate. Thus, the first throwing belt 48 and the second throwing belt 49 are rotated in opposite directions. That is, for example, when the drive motor 62 normally rotates, as shown in FIG. 4, the first ejection belt 48 normally rotates in the direction in which the product 9 is pushed out from the first storage space 25 by the ejection member 51, The second throwing belt 49 reverses in the direction in which the product 9 is not pushed out by the withdrawal of the throwing member 51. Further, as the rotation direction of the drive motor 62 is reversed and reversed, as shown in FIG. 5, the first throwing belt 48 is reversed in the direction in which the product 9 is not pushed out by the withdrawal of the throwing member 51, The second throwing belt 49 rotates forward in the direction in which the product 9 is pushed out from the second storage space 26.
[0026]
  When the drive motor 62 is not driven, the throwing member 51 is in a position corresponding to the front pulley 46 and the rear pulley 47, as shown in FIG.ThatIt is not in the first storage space 25 and the second storage space 26, but is in a standby state in a state of being positioned in the front-rear direction. In the drive motor 62, the first throwing belt 48 and the second throwing belt 49 are half-turned, that is, one of the throwing members 51 positioned in the standby state is the first storing space 25 and the second storing. The drive control is performed so as to stop when it passes through the space 26 and is positioned in the standby state at the opposite symmetrical position.
[0027]
  Further, by attaching the column member 22 above the product dispensing unit 21, a dispensing opening 74 through which the product 9 can pass between the upper surface of the product dispensing unit 21 and the lower end edge of the front support portion 28 is provided. Is open. Further, between the upper surface of the product dispensing unit 21 and the lower end edge of the rear surface portion 23, a dispensing member 51 provided on each of the first dispensing belt 48 and the second dispensing belt 49 can pass. In addition, a relief opening 75 through which the product 9 cannot pass is formed.
[0028]
  Next, the assembly operation of the above embodiment will be described.
[0029]
  The product projection unit 21 is attached and fixed by engaging the engaging claws 40 and 40 of the product delivery unit 21 in an attachment hole (not shown) opened in the shelf plate 4 attached to the main body 2 in advance. Next, the second insertion projection 33 provided on the second partition plate 27 of the column member 22 is inserted and held in the insertion hole 43 of the product dispensing unit 21 and the insertion hole provided on the shelf plate 4 The column member 22 is attached and fixed by inserting and holding the first insertion protrusion 32 at 31.
[0030]
  Then, an unillustrated connector provided on the main body 2 in advance is provided with an unillustrated connector provided on an electric wire for supplying power to an unillustrated drive motor 62 of the merchandise dispensing unit 21 and a signal line for transmitting a signal of the merchandise detection unit. Connect to the connector.
[0031]
  On the other hand, in the case of replacement of the product dispensing unit 21, the column member 22 is removed, and the latching claw portions 40, 40 having elasticity of the product dispensing unit 21 are elastically deformed and removed from the mounting holes of the shelf board 4. Then, the product dispensing unit 21 is removed.
[0032]
  Next, the operation of dispensing the product of the above embodiment will be described with reference to FIGS.
[0033]
  First, the products 9 are stored in the product columns 6 and 6 in an integrated state, the power is turned on, and the dispensing members 51 and 51 shown in FIG. 3 are located in the first storage space 25 and the second storage space 26. Do not wait. In this standby state, as shown in FIG. 3, the throwing members 51 and 51 are not located in the first storage space 25 and the second storage space 26, and correspond to the front pulley 46 and the rear pulley 47. It is in a state of being positioned forward and backward. In addition, since the product 9 is stored in the first storage space 25 and the second storage space 26 of the product column 6, the detection unit 58 of the product detection unit 59 is pushed by its own weight. By detecting the product 9 by retreating from the upper end surface of the case body 35, a control device (not shown) controls not to display “out of stock”.
[0034]
  In this standby state, the user performs a purchase operation, that is, inserts money and operates the selection button. By operating this selection button, the control device drives the drive motor 62 of the corresponding product column 6.
[0035]
  That is, for example, when the selected product 9 is the product 9 stored in the first storage space 25 of the predetermined product column 6, the drive motor 62 of the product column 6 is rotated forward. Due to the forward rotation of the drive motor 62, as shown in FIG. 4, a first gear transmission 63 that engages with the first gear gear 63 is rotated by the first gear gear 63 provided on the output shaft 61 of the first drive motor 62. The first transmission tooth gear 67a of the portion 70 and the second transmission tooth gear 67b of the second drive transmission portion 71 rotate in opposite directions. The first transmission small gear 68a and the second transmission small gear 68b that engage with the first transmission small gear gear 67a and the second small gear gear 67b, respectively, and the first transmission small gear 68a and The rear pulley 47 and the second throwing mechanism of the first throwing mechanism portion 37 are connected via the first large transmission gear 69a and the second large transmission gear 69b engaged with the second small transmission gear 68b. The rotation in the opposite direction is transmitted to the rear pulley 47 of the portion 38.
[0036]
  Then, the rear pulley 47 of the first throwing mechanism portion 37 is rotated forward, and the first throwing belt 48 is rotated forward, that is, biased by the urging means of the pushing portions 53, 53 of the throwing members 51, 51. The first throwing belt 48 rotates so that the side away from the outer surface of the first throwing belt 48 becomes the front side in the moving direction.
[0037]
  By forward rotation of the first throwing belt 48, as shown in FIG. 9A, the end edge on the rotating side of the pushing portion 53 of the throwing member 51 is displaced from the escape opening 75 into the first storage space. 9B, as shown in FIG. 9B, the push-out portion 53 comes into contact with the lowest product 9 stored in the first storage space 25 in an accumulated state. The product 9 is discharged through the dispensing opening 74 and the product 9 is sent to the product chute 14 as shown in FIG. The product 9 sent to the product chute 14 is thrown out to the product take-out part 11 that passes through the product chute 14 and opens the product take-out port. When the throwing members 51 and 51 move to the standby position, the control device stops driving the drive motor 62 and enters the standby state again. Further, as the lowest product 9 is pushed out, the product 9 located in the first storage space 25 moves downward as a whole as shown in FIG. The detection unit 58 is pushed in. When all the products 9 are thrown out, the detection unit 58 of the product detection unit 59 is not pushed, and the control device recognizes that there is no product 9 and displays “sold out (out of stock)”.
[0038]
  On the other hand, the rear pulley 47 of the second throwing mechanism portion 38 is reversed and the second throwing belt 49 is reversely rotated, that is, the shaft-supported side of the pushing portions 53 and 53 of the throwing members 51 and 51 is in the moving direction. The second throwing belt 49 rotates so as to be on the front side.
[0039]
  By the reverse rotation of the second throwing belt 49, the shaft support side of the pushing portion 53 of the throwing member 51 moves from the throwing opening 74 into the second storage space 26 as shown in FIG. . Then, as shown in FIG. 10 (b), the pushing portion 53 rotates toward the second throwing belt 49 against the urging force of the urging means by the weight of the product 9, and the pushing portion 53 The rotation side moves so as to slide on the lower surface of the lowest product 9. Here, since the lowest product 9 is positioned on the rear surface portion 23 of the column member 22, the product 9 is not thrown out of the second storage space 26. Then, the throwing members 51 and 51 move to the standby state position, the drive of the drive motor 62 is stopped, and the standby state is entered again.
[0040]
  If the product 9 selected by the operation of the selection button is the product 9 stored in the second storage space 26 of the predetermined product column 6, the drive motor 62 of the product column 6 is reversed, and FIG. As shown in FIG. 4, the first throwing belt 48 is rotated in the reverse direction and the second throwing belt 49 is rotated in the forward direction. Similarly, the lowest product 9 stored in the second storage space 26 in an accumulated state. Throw out.
[0041]
  Thus, corresponding to the forward / reverse rotation of the drive motor 62 capable of forward / reverse rotation, the first storage space 25 and the first storage space 25 of the pair of product columns 6 which are adjacent to each other by the drive transmission means 72 and store the products 9 in an integrated state. The product 9 located at the lowest position stored by rotating one of the first throwing mechanism 37 and the second throwing mechanism 38 disposed respectively below the second storage space 26 is thrown. Since the product 9 is not thrown out by reversing the other of the first throwing mechanism part 37 and the second throwing mechanism part 38, the two first storage spaces 25 are driven by one drive motor 62. The product 9 stored in the second storage space 26 can be appropriately thrown out, and there is no need to provide each of the drive motors 62 corresponding to the type of the product 9, that is, the location where the product 9 is stored. Can reduce the number of heavy drive motors 62, improve productivity and reduce costs Can be reduced, it can be easily lightweight miniaturization.
[0042]
  Further, since the first ejection belt 48 is provided with the ejection member 51 that pivotally supports the pushing portion 53 urged by the urging means so as to be rotatable, the drive transmission means 72 is simply connected to the first ejection belt 48. By adopting a configuration in which the drive is transmitted so as to rotate the 48 and the second dispensing belt 49 in the opposite directions, a configuration in which the two types of products 9 can be suitably dispensed with one drive motor 62 can be easily obtained.
[0043]
  Since the case body 35 made of synthetic resin having elasticity is used, noise generated when driving of the drive motor 62 is transmitted to the first throwing belt 48 and the second throwing belt 49 by the drive transmission means 72. Can be suppressed.
[0044]
  In the above embodiment, the drive transmission means 72 is constituted by the bevel gear 63, the first drive transmission section 70, and the second drive transmission section 71. However, the drive transmission means 72 corresponds to the forward / reverse rotation of the drive means. Any configuration in which the first throwing mechanism portion 37 and the second throwing mechanism portion 38 are appropriately driven in opposite directions can be employed. By using the bevel gear 63, it can be easily driven in the opposite direction with a simple configuration.
[0045]
  Next, another embodiment of the present invention will be described with reference to FIGS.
[0046]
  In the embodiment shown in FIGS. 11 to 15, the drive transmission means 72 of the embodiment shown in FIGS.

The configuration is such that the transmission of the drive is cut off and the product 9 is not thrown out.
[0047]
  That is, the product dispensing unit 81 has the first dispensing mechanism 82 and the second dispensing with the ribs 36 and 36 in the same manner as the product dispensing unit 21 of the embodiment shown in FIGS. The mechanism unit 83 and the drive unit 84 are partitioned, and the case body 35 is provided with a locking claw portion 40 protruding therefrom.
[0048]
  The first throwing mechanism portion 82 and the second throwing mechanism portion 83 include the first throwing mechanism portion 37 and the second throwing mechanism portion 38 of the embodiment shown in FIGS. In the same manner as the above, a first throwing belt 48 and a second throwing belt 49 that are stretched around a front pulley 46 and a rear pulley 47 that are rotatably supported on a rotating shaft 45 are provided. Further, a plurality of, for example, two throwing members 85, 85 are provided on the outer peripheral surfaces of the first throwing belt 48 and the second throwing belt 49, for example, at positions that are roughly divided into two in the circumferential direction. Yes. The throwing member 85 is formed in a wedge shape in cross section with, for example, a synthetic resin, and is provided with an inclined surface 86 so as to become gradually thinner, and a contact surface 87 for pushing out a product on the end face of the thick portion. The contact surface 87 is attached so as to be substantially perpendicular to the outer peripheral surfaces of the first and second ejection belts 48 and 49.
[0049]
  On the other hand, the drive unit 84 includes a drive motor 62 having a bevel gear 63 on the output shaft 61 in the same manner as the drive unit 39 of the embodiment shown in FIGS. In addition, the drive unit 84 has a pair of rotating shafts 65 and 65 that are positioned in the radial direction of the gear tooth gear 63 in the radial direction and whose axial direction is substantially perpendicular to the output shaft 61 of the drive motor 62 and that is substantially coaxial with each other along the horizontal direction. Arranged freely. The rotary shafts 65, 65 have a first transmission gear gear 67 a and a second transmission gear gear 67 b that constitute drive transmission means that engages with the gear gear 63, and the rotation shaft 65 in one direction. A one-way clutch 88 that meshes only when rotating in the reverse direction and rotates in the opposite direction is provided. Further, a first transmission small gear 68a and a second transmission small gear 68b are pivotally supported by these one-way clutches 88, 88. The first transmission small gear 68a and the second transmission small gear 68b are respectively provided with a first transmission large gear 69a and a first transmission large gear 69a and a first transmission large gear 69a, which are integrally provided on the rotary shafts 45 and 45 that support the rear pulleys 47 and 47, respectively. The second large transmission gear 69b is engaged.
[0050]
  Note that the one-way clutches 88, 88, for example, when the drive motor rotates normally, as shown in FIG. The first transmission small gear 68a is rotated by the rotation of the rotary shaft 65 and the second transmission small gear 68b is idled so that the drive is not transmitted and does not rotate. 15 reversely rotate, the first transmission small gear 68a is idled so that the first transmission small gear 68b rotates without being driven and not rotated as shown in FIG. The small gear 68a and the second transmission small gear 68b rotate in the relatively opposite directions.
[0051]
  The first transmission gear gear 67a, the first transmission small gear 68a pivotally supported by the one-way clutch 88, and the first transmission large gear 69a constitute a first drive transmission portion 91. The second transmission transmission portion 92 is constituted by the transmission transmission gear gear 67b, the second transmission small gear 68b supported by the one-way clutch 88 and the second transmission large gear 69b. In addition, the first driving belt 91 and the second driving belt 92 and the bevel gear 63 rotate the first throwing belt 48 and the second throwing belt 49 by driving the drive motor 62. Drive transmission means 93 for transmitting the drive to be performed is configured.
[0052]
  Next, the operation of the embodiment shown in FIGS. 11 to 15 will be described.
[0053]
  In the standby state, the user inserts a purchase operation, that is, inserts money, and operates the selection button to drive the drive motor 62 of the corresponding product column 6 by the control device.
[0054]
  That is, for example, when the selected product 9 is the product 9 stored in the first storage space 25 of the predetermined product column 6, the drive motor 62 of the product column 6 is rotated forward. Due to the forward rotation of the drive motor 62, as shown in FIG. 14, a first gear transmission 63 that engages with the second gear gear 63 is rotated forward by the first gear gear 63 provided on the output shaft 61 of the second drive motor 62. The first transmission tooth gear 67a of the portion 91 and the second transmission tooth gear 67b of the second drive transmission portion 92 rotate integrally with the rotary shafts 65 and 65 in opposite directions, respectively. Then, the one-way clutch 88 of the first drive transmission unit 91 is engaged and the first transmission small gear 68a rotates, and the one-way clutch 88 of the second drive transmission unit 92 rotates idly and the second transmission small gear 68b is Does not rotate. For this reason, the first throwing mechanism portion 82 is rotated by the drive transmitted to the first transmission large gear 69a meshing with the rotating first transmission small gear 68a, and the rear pulley 47 rotates in the forward direction.
[0055]
  Then, the rear pulley 47 of the first throwing mechanism portion 82 is rotated forward so that the first throwing belt 48 is rotated forward, that is, the contact surface 87 side of the throwing members 85 and 85 is the front side in the moving direction. At this time, the first throwing belt 48 rotates and the product 9 in the first storage space 25 is thrown out.
[0056]
  On the other hand, the second throwing mechanism 83 is not transmitted to the meshing second transmission large gear 69b by the idle second transmission small gear 68b, and the second transmission large gear 69b does not rotate. The rear pulley 47 does not rotate forward. For this reason, the goods 9 in the 2nd storage space 26 are not thrown out by not rotating normally with the 2nd throwing-out belt 49 stopped.
[0057]
  If the product 9 selected by operating the selection button is the product 9 stored in the second storage space 26 of the predetermined product column 6, the drive motor 62 of the product column 6 is similarly reversed, As shown in FIG. 15, the first throwing belt 48 of the first throwing mechanism portion 82 does not rotate, the second throwing belt 49 of the second throwing mechanism portion 83 rotates forward, The product 9 in the second storage space 26 is thrown out.
[0058]
  Thus, corresponding to the forward / reverse rotation of the drive motor 62 capable of forward / reverse rotation, the first storage space 25 and the first storage space 25 of the pair of product columns 6 which are adjacent to each other by the drive transmission means 93 and store the products 9 in an integrated state. The product 9 positioned at the lowest position stored by rotating one of the first throwing mechanism part 82 and the second throwing mechanism part 83 respectively disposed below the two storage spaces 26 is thrown. Since the transmission of the drive motor 62 to the other one of the first throwing mechanism part 82 and the second throwing mechanism part 83 is cut off and the product 9 is not thrown out, one drive motor 62 The products 9 stored in the two first storage spaces 25 and the second storage space 26 can be appropriately thrown out, and it is necessary to provide drive motors 62 corresponding to the types of the products 9, that is, the locations where the products 9 are stored. In particular, the number of heavy drive motors 62 with coils can be reduced and productivity is reduced. It can be improved and the cost can be reduced, and it can be easily reduced in weight and size.
[0059]
  Further, in response to the forward / reverse rotation of the drive motor 62, the drive is transmitted to one of the first throwing mechanism part 82 and the second throwing mechanism part 83, and the product 9 is thrown out to either one. Since the one-way clutches 88 and 88 are used as a configuration that does not transmit the drive, the product 9 stored in the two first storage spaces 25 and the second storage space 26 by one drive motor 62 with a simple structure is appropriately used. Can throw out.
[0060]
  Furthermore, since only one of the first throwing mechanism part 82 and the second throwing mechanism part 83 is driven when the product 9 is thrown out, as compared with the embodiment shown in FIGS. Therefore, the generation of noise can be further suppressed.
[0061]
  Similarly to the embodiment shown in FIGS. 1 to 10, since the case body 35 made of synthetic resin having elasticity is used, the drive motor 62 is driven by the drive transmission means 72 and the first throwing belt 48 and It is possible to suppress the generation of noise that occurs when transmitting to the second throwing belt 49.
[0062]
  In the embodiment shown in FIGS. 1 to 10 and the embodiment shown in FIGS. 11 to 15, the vending machine that sells cigarettes has been described. For example, other cans such as soft drinks can be used. You can do either. The column member 22 is formed in an appropriate shape according to the shape of the product 9, and the throwing member 51 is also appropriately extruded according to the shape of the product 9 or formed in an appropriate shape that can be pulled out by hooking the product 9.
[0063]
  TheFurthermore, in the embodiment shown in FIGS. 11 to 15, the drive transmission means 93 includes a first drive transmission portion 91 and a second drive transmission portion 92 provided with a bevel gear 63 and a one-way clutch 88. Although configured, in response to forward / reverse rotation of the driving means, only one of the first throwing mechanism portion 82 and the second throwing mechanism portion 83 is driven to rotate forward and throw the product 9 out. Any configuration can be used.
[0064]
【The invention's effect】
  According to the product dispensing apparatus of the vending machine according to claim 1, either one of the product dispensing means is rotated forward by the drive transmission means in response to the forward / reverse rotation of the drive means capable of forward / reverse rotation. Since one of the pair of adjacent product storage units is thrown out, and the other is reversed so that the product is not thrown out, the products in the two product storage units are appropriately thrown out by one driving means. In addition, it is not necessary to provide a driving means corresponding to the product storage section, so that the productivity can be improved, the cost can be reduced, and the weight and the size can be easily reduced.
[0065]
  According to the product dispensing apparatus of the vending machine according to claim 2, either one of the product dispensing means is rotated forward by the drive transmission means in response to the forward / reverse rotation of the drive means capable of forward / reverse rotation. Since one product of a pair of adjacent product storage units is thrown out and the transmission of the drive to either one is interrupted and the product is not thrown out, one drive means can be used in the two product storage units. The product can be thrown out as appropriate, and it is not necessary to provide a driving means corresponding to the product storage portion, so that the productivity can be improved, the cost can be reduced, and the light weight and the size can be easily reduced.
